The development of precise folding techniques for synthetic polymer chains that replicate the unique structures and functions of biopolymers has long been a key challenge. In particular, spiro-type (i.e., 8-, trefoil-, and quatrefoil-shaped) polymer topologies remain challenging due to their inherent structural comple…
Abstract By employing a set of resonators with extended necks, an ultrathin acoustic carpet cloak with a thickness of about 1/30th of the operation wavelength is proposed to achieve effective cloaking around a bump at 1000 Hz. The cloak is composed of a periodic array of supercells. The supercell is constructed by a s…
Underwater superoleophobic microlens array (MLA) has been emerging as a crucial device for its wide applications in ocean optical imaging and sensing, endoscopic surgery, microfluidics and optofluidics, and other biomedical applications. Fabrication of microlens arrays integrated with excellent optical performance as…
This paper reports on a tunable transmission frequency characteristics-based metamaterial absorber of an X band sensing application with a fractional bandwidth. Tunable resonator metamaterial absorbers fabricated with dielectric surface have been the subject of growing attention of late. Absorbers possess electromagne…
Abstract We introduce laser cavitation rheology (LCR) as a minimally-invasive optical method to characterize mechanical properties within the interior of biological and synthetic aqueous soft materials at high strain-rates. We utilized time-resolved photography to measure cavitation bubble dynamics generated by the de…
Abstract Recently, Li‐ion batteries (LIBs) have attracted extensive attention owing to their wide applications in portable and flexible electronic devices. Such a huge market for LIBs has caused an ever‐increasing demand for excellent mechanical flexibility, outstanding cycling life, and electrodes with superior rate…
Acute and chronic arsenic (As) toxicity is a global health issue affecting millions of people, which leads to inactivation of over 200 enzymes, particularly those involved in cellular energy pathways and DNA synthesis and repair. The fern Pteris vittata acts as a hyperaccumulator of As and may be useful for phytoremed…
High concentrations of creatinine and urea in the blood can be removed by dialysis using semipermeable membranes that are selective for certain species and hold other species through diffusion processes. This ability requires a membrane that has an active side, which functions as a targeted species identifier. The mem…
In this paper, we perform all-atom molecular dynamics (AA-MD) simulations to predict noise in solid-state nanopores. The simulation system consists of ∼70,000 to ∼350,000 atoms. The simulations are carried out for ∼1.3 µs over ∼6500 CPU hours in 128 processors (Intel® E5-2670 2.6 GHz Processor). We observe low and hig…
Blast walls are installed on the topside of offshore structures to reduce the damage from fire and explosion accidents. The blast walls on production platforms such as floating production storage, offloading, and floating production units undergo fire and explosion risk analysis, but information about blast walls on t…
Sandwich composites with polymeric open-celled foams or honeycomb structures as core materials have been used widely in low-weight naval, aerospace and structural applications in the past. One major drawback of such foams is skin-core debonding. To overcome this, core materials with the same matrix as the skin are stu…
Proximity-effect-induced superconductivity is studied for high-quality ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}/\mathrm{Fe}{\mathrm{Se}}_{0.5}{\mathrm{Te}}_{0.5}$ (FST) thin-film heterostructures with atomically sharp interfaces and for ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}/{\mathrm{TiO}}_{2}$/FST heterostructures where ${\m…
Carbon based electrodes suitable for integration with CMOS readout electronics are of great importance for a variety of emerging applications. In this study, we have looked into the prerequisites for the optimized pyrolytic conversion of 3D printed polymer microstructures and nanostructures with the goal of developing…
In traditional optical design, a starting point is selected and coefficients optimization is then performed using software. The process requires considerable time and the involvement of a human with design skills and experience. In this Letter, a fast automatic method for freeform imaging systems design is proposed. U…
Doxorubicin (DOX) is commonly used as an anti-cancer agent. However, its severe cardiotoxicity often makes it life threatening even long after DOX therapy during childhood. We recently reported interferon-γ (IFN-γ) necessary for DOX-induced acute cardiotoxicity in a p38 dependent way and, asked here for the potential…
Heterometallic metal organic frameworks (MOF) have attracted huge interest for a wide range of applications including gas storage, separation, and catalysis owing to their tunable electronic and magnetic properties. Among several heterometallic MOF structures reported, iron containing MOF structure, namely PCN-250, ex…
Abstract Alzheimer’s disease (AD) is the most prevalent cause of dementia linked to the accumulation of amyloid-beta (Aβ) plaques-fibrils that impair cognitive functions. Magnetic nanoparticles (MNPs) are emerging as promising tools for the crusade against AD owning to appropriate biocompatibility and facile functiona…
values of 277.17 and 290.00 μM, respectively, and inhibited the release of β-TG and 5-HT in a dose-dependent manner significantly. Single oral administration of OGEFG and DEGP also inhibited thrombus formation in a ferric chloride-induced arterial thrombosis model at a dose of 200 μmol/kg body weight and did not prolo…
The development of new, improved zeolitic materials is of prime importance to progress heterogeneous catalysis and adsorption technologies. The zeolite HZSM-5 and metal oxide γ-Al2O3 are key materials for processing bio-alcohols, but both have some limitations, i.e., HZSM-5 has a high activity but low catalytic stabil…
Abstract The radial conjugated π‐system of cycloparaphenylenes (CPPs) makes them intriguing fluorophores and unique supramolecular hosts. However, the bright photoluminescence (PL) of CPPs was limited to the blue light and the supramolecular assembly behavior of large CPPs was rarely investigated. Here we present the…
